Molecules and Processes of Life Activity 6 - Cellular Respiration and the Effects of Pollutants on Its Rate - science lab Report ExampleThe amount of gas emitted at the top of tube was observed to over 10 minutes so as to determine cellular ventilation system rate. The pollutants used included vinegar, salt solution, isopropyl alcohol, bake soda, soap solution, and bleach solution.The result for yeast mixture was compared with the results for yeast-sugar mixture. The yeast-sugar mixture exhibited a faster cellular respiration rate. The outcomes of the pollutants had mixed results. Except baking soda, most of the pollutants utilized had a lower cellular respiration rate. harmonise to Carpenter (2013), cellular respiration is a process in which chemical energy in the viands is reaped and converted into energy that is utilized in carrying out the normal life process. Every organism requires cellular respiration for survival. This process happens in three distinct phases glycolysis, Krebs cycle, and electron transport chain. Lippmann (2009) argues that during these cycles, atomic number 8 and glucose in our dead body are turned into carbon dioxide, energy, and water. The first phase of cellular respiration is when one glucose molecule is sever to produce two pyruvic acid molecules, a 3-carbon compound (Schapira, McQuaid & Froneman, 2011). This first phase is anaerobic, implying it does not need oxygen to occur. The remaining phases require oxygen. As much(prenominal), the experiment was conducted within an oxygen zone and a considerable measure frame to allow the three phases of cellular respiration to occur.To test our first hypothesis, the experimental design was such that yeast was mixed with water then poured into a test tube. A wider test tube was primed(p) over the yeast test tube and flipped together over 10 minutes to observe the take aim of gas amounting in the wider tube. The amount of gas was recorded every minute in the10 minutes. The same was through to a yeast-water mixture but with granulated sugar added into
